Abstract

The invention provides an oil-gas separator. The oil-gas separator comprises a first shell, a first separator, a second separator and a control valve assembly. The first shell is provided with an oil-gas inlet, a first channel and a second channel, wherein the first channel and the second channel are arranged in a spaced manner. The first separator communicates with the first channel. The second separator communicates with the second channel. The control valve assembly is arranged in the first shell, and the oil-gas inlet selectively communicates with the first channel and / or the second channel through the control valve assembly. The first separator and / or the second separator are / is of a spiral separation structure. By means of the provided technical scheme, the technical problem that anoil-gas separator in the prior art is low in separation efficiency can be solved.

Description

technical field [0001] The invention relates to the technical field of automobile engines, in particular to an oil-gas separator. Background technique [0002] When the automobile engine is working, part of the gas in the combustion chamber of the combustion chamber will escape into the crankcase with the reciprocating motion of the piston. These gases generally enter the combustion chamber again through the crankcase ventilation system to participate in combustion and discharge. With the development of engine technology, the particle diameter of engine oil in the crankcase is greatly reduced compared with before, and the crankcase gas is more likely to carry a large number of oil particles out of the crankcase, resulting in high oil consumption. Therefore, an efficient oil-gas separation system is necessary. [0003] In the field of automobile engines, passive oil-gas separators are currently used. Common passive oil-gas separators can be divided into centrifugal, impact a...
